# List information about objects in an S3 bucket
#
# ==== Parameters
# * bucket_name<~String> - name of bucket to list object keys from
# * options<~Hash> - config arguments for list. Defaults to {}.
# * 'delimiter'<~String> - causes keys with the same string between the prefix
# value and the first occurence of delimiter to be rolled up
# * 'marker'<~String> - limits object keys to only those that appear
# lexicographically after its value.
# * 'max-keys'<~Integer> - limits number of object keys returned
# * 'prefix'<~String> - limits object keys to those beginning with its value.
#
# ==== Returns
# * response<~Excon::Response>:
# * body<~Hash>:
# * 'Delimeter'<~String> - Delimiter specified for query
# * 'IsTruncated'<~Boolean> - Whether or not the listing is truncated
# * 'Marker'<~String> - Marker specified for query
# * 'MaxKeys'<~Integer> - Maximum number of keys specified for query
# * 'Name'<~String> - Name of the bucket
# * 'Prefix'<~String> - Prefix specified for query
# * 'Contents'<~Array>:
# * 'ETag'<~String>: Etag of object
# * 'Key'<~String>: Name of object
# * 'LastModified'<~String>: Timestamp of last modification of object
# * 'Owner'<~Hash>:
# * 'DisplayName'<~String> - Display name of object owner
# * 'ID'<~String> - Id of object owner
# * 'Size'<~Integer> - Size of object
# * 'StorageClass'<~String> - Storage class of object
